Abstract
The current investigation aimed to analyze growth and growth related attributes involving fifty tomato genotypes including three control varieties under low tunnel, paddy straw and open field conditions. The trial was carried out in Randomized Block Design (RBD) with three replications over two years 2020-2021 and 2021-2022 Rabi season at Faculty of Agriculture, Vegetable farm, Guru Kashi University, Talwandi Sabo, Bathinda. The analysis of variance depicted significantly high amount of variability among different genotypes for all the parameters. The maximum data for plant height was recorded in the genotype S-115 (220.54 cm) under low tunnel conditions. Maximum number of primary branches were recorded in S-115 (18.66). Days to first flowering was revealed in S-115 (33.21 days), days to first fruit set was observed in S-115 (72.56). Maximum value for days to first fruit harvest and last fruit harvest was observed in S-115 (102.56 days) and (177.24 days) respectively. The mean performances of genotypes depicted wide variations over various environments for all the parameters under research.
